SPECIFICATION frmng pm 0f Lettera Patent N0. 711,008, dated October 14, 1903.

Application led Huch 8. 1902. Serial Fo. 97,884. (No model.)

To* au whom. it -my confsern.-

Beit known that l, ALEXANDER ANDERSON SCo'lr, a citizen of the United States. residing in the city of Knoxville, in the countyof Knox 5 and State of Tennessee, have invented cer tain new and useful Improvementsin Elevatingf'lrucks, of which the following is a specifi- ,catlom My invention relates to trucks for carrying xo heavy loads, such as pallets of molded brick, dsc., and has for its object to provide a device thatrwill reduce to a minimum vthe friction incident to raising and lowering the platform. The construction of my invention is fully x5 disclosed in the drawings, in which- Figure 1 is a side view in elevation of my f invention, showing the platform lowered for receiving the load; Fig. 2, alike view show ing the platform in an elevated position; Fig. :o 3, a front view, and Fig. 4 a detail view, of i the operating lever or handle.

Referring to the drawings, in which similar reference characters indicate corresponding parts throughout the several views, A represents the base-frame of my truck, ,B the axles journaled in the brackets C, and D the 1 .l wheels keyed to said axles.

E represents the platform, which is in reality alframe of another truck, having axles F, journaled in brackets G, and wheels H, keyed to said axles. The wheels Hare preferably flanged, and the tread' is intended to travel in the side beams of the base-frame Aand on i "the blocks I, secured to said side beams having inclined surfaces t', up which the wheels II areadapted to travel to raise the platformvE.

if K represents standards at the front of the Y base-frame, haviugears L secured thereto, between each pair of which are pivoted one of the arms of the Y-shaped handle or lever M, and N links, pivotally connecting the handle 1M with the front of the platform E.

O represents stops at the rear of the basel f rame A to limit the backward movement of the upper truck or elevating-platform.

It will be readily understood that when wheels H of the upper truck are resting on the side beams of the frame A the platform E is in a lowered position and may be run undcrits load, the handle M being in a raised position. The handle is then depressed, pulling forward the upper truck, the wheels of which travel up the incline i and rest on the top of the blocks I when the platform E is in 6o frames, and the truck may be removed and is ready to repeat the above operation.

Having thus described my invention, what I claim is l A l. In an elevating-truck` side beams hav- 65 ing wheels jou rnaled thereon formingthe run ning-gear of the truck, blocks secured to the upper side of said side beams each block having a rearwardly-extending inclined surface, an elevating-platform comprising a wheeled truck adapted to travel ony said side beams and blocks, and means to actuate said platform-truck, substantially as shown and do'. scribed.

2. In an elevatii-ig-truck, a. base-frame, blocks secured on said base-frame having iuclined surfaces toward the rear of the truck, a platform, wheels journaled tosaid platform Y. to ride on the side beams of said base-frame and said blocks, uprights at the front of said 8e 'base-frame, a U-shapcd yhandle pivoted to said uprights, links connectingsaid handle with the front of tt L.latfoi-xxl, andstops at the rear of the baer :rame to limit the backward movement ot' said wheeled platform, 85 substantially as shown and described.

3. An elevating-trnck consisting of a baseframe, brackets secured thereon, wheels jour-l naled in said brackets, blocks secured to them. side beams of said base-frame having rear wardly-inclined surfaces, uprights secured the front of said base-beams, cars secure said uprights, a V-shaped handle journwct. inv said ears, an elevating-platform having Y brackets secured to the sde'beams thereof, 95" wheels jou rnaled in said brackets adapted to Y travel on the side beams of the base-frame and the blocks secured thereto, links connecting the front of said platform with said V- shaped handle, and stops at the rear of the baseframo side bcains,siibstaxitiall y as shown and described.

In testimony whereof I hernie allie. my signature in thc presence of two witnesses.

ALEXANDER ANDERSX SCOTT.
